表示推测的情态动词在英语中，表示对某件事物的确定程度，即表示推测的时候，我们通常会用到以下情态动词:must,might,could,may,can’t,couldn’t。可能性：must>can/could>may/mightcannot(can’t)couldnot(couldn’t)maynotmightnot一、mustmust“一定、准是”。只能用于肯定句。

“一定不”，应该用can't。如果询问可能性时，应该用can。Hemustknowtheanswers.

他肯定知道答案。Hecan'tknowtheanswers.

他肯定不知道答案Canheknowtheanswer?

他知道答案吗？二、can/couldcan表示推测“可能性”时，一般用于否定句或疑问句。can在疑问句中意思是“会，可能”。Hecan’tpickherschoolbagup.

他不可能拿了她的书包。

could表示某事有可能发生或可能是事实。Don’teatit.Itcouldgobad.

不要吃它，可能坏了。Theplanecouldbeputoffbythestorm.

这趟飞机可能会因为暴风雨而推迟。

could还可用于表示客气、礼貌、委婉的请求语气。Couldyoupleasehelpmewithmyhomework?

你能帮我完成我的家庭作业吗？

三、may/mightmay,might表示推测“可能性”时，意思是“可能”，“也许”。might不表示过去时态，语气更委婉，可能性更小。may,might表推测时，用于否定句，但不用于疑问句。Hemay/mightnotbeathome,butI'mnotsure.

他可能不在家，不过我也不确定。
